Recently a customer got fooled into thinking that AntiVirus 2009 was a legitimate antivirus program and somehow downloaded the program.
Suffice it to say that Anti Virus 2009 is really another sad bit of spyware disguised as a legitimate program.
Luckily it seems easy to remove. Just download Malwarebytes’ Anti-Malware program and run a quick scan to remove the Antivirus 2009 spyware.
